WebApr 28, 2024 · Optoacoustic or photoacoustic imaging (OAI/PAI) is a technology which enables non-invasive visualization of laser-illuminated tissue by the detection of acoustic signals. The combination of “light in” and “sound out” offers unprecedented scalability with a high penetration depth and resolution. The wide range of biomedical applications makes … Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect. Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband … See more The optical absorption in biological tissues can be due to endogenous molecules such as hemoglobin or melanin, or exogenously delivered contrast agents. As an example, Fig. 2 shows the optical absorption spectra of See more General equation Given the heating function $${\displaystyle H({\vec {r}},t)}$$, the generation and propagation of photoacoustic wave pressure $${\displaystyle p({\vec {r}},t)}$$ in an acoustically homogeneous inviscid medium is governed … See more Photoacoustic imaging has seen recent advances through the integration of deep learning principles and compressed sensing.

This article provides an overview of the rapidly expanding field of photoacoustic imaging for biomedical applications.
WebThe focus is on two particular technologies: fluorescence molecular imaging and optoacoustic (photoacoustic) imaging. The rationale for the selection of these two methods is that in contrast to optical microscopy techniques, both fluorescence and optoacoustic imaging can achieve large fields of view, i.e., spanning several centimeters in two or ...
